evolution of computer describing the technologies used in different generations. The evolution of computers started way back in the late 1930s. Binary arithmetic is at the core of the computers of all times. History of computers dates back to the invention of a mechanical adding machine in 1642. Abacus‚ an early computing tool‚ invention of logarithm by John Napier and the invention of slide rules by William Oughtred were significant events in the evolution of computers.

Design of computers In 1812 he was sitting in his rooms in the Analytical Society looking at a table of logarithms‚ which he knew to be full of mistakes‚ when the idea occurred to him of computing all tabular functions by machinery. The French government had produced several tables by a new method. Three or four of their mathematicians decided how to compute the tables‚ half a dozen more broke down the operations into simple stages‚ and the work itself‚ which was restricted to addition and subtraction

HISTORY OF COMPUTERS The abacus was an early aid for mathematical computations. Its only value is that it aids the memory of the human performing the calculation. A skilled abacus operator can work on addition and subtraction problems at the speed of a person equipped with a hand calculator. The abacus is often wrongly attributed to China. In fact‚ the oldest surviving abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today‚ principally in the far east. A modern abacus
